THE MOON ROCKET
CHALLENGE

When
the Space Race began, there was no rocket powerful enough to send
a man to the Moon and back. Both the Americans and the Soviets had
to develop a super-booster, or Moon rocket. The United States succeeded
with the mighty Saturn V. The Soviets' N-1 Moon rocket never made
it into space.

Both
the United States and the Soviet Union began their separate quests
for a Moon rocket by scaling up existing smaller rockets into gigantic
multi-stage launch vehicles.
